What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Work-related musculoskeletal disorders (MSDs) are a significant public health problem for individuals engaged in tasks involving repetitive upper limb movements and extended computer use, including those working in the social security sector. The International Labor Organization (ILO) has listed musculoskeletal disorders as an occupational disease that requires preventive measures in workplaces. However, there is limited information in the context of Tanzania. Therefore, this study aimed to address this knowledge gap, focusing on the magnitude and risk factors of MSDs among social security workers in Dar es Salaam. Objective: This study aimed to assess the work-related musculoskeletal disorders and the contributing risk factors among social security workers in Dar es Salaam. Materials and methods: The study used a cross-sectional design and included a sample of 300 employed social security workers working at NSSF offices in the Dar es Salaam region. The study included all NSSF workplaces in Dar es Salaam, and eligible participants were selected using probability proportional to size. Data were collected using a structured Nordic questionnaire to determine the prevalence and factors contributing to MSDs. In contrast, a checklist was used to identify preventive measures and factors contributing to MSDs. A modified Poisson model of analysis was used to analyse the factors contributing to MSDs. Results: The overall prevalence of MSDs reported by participants in the previous 12 months was 77.7%. The significant risk factors for MSDs included lower education levels (aRR: 1.71; 95% CI: 1.140-2.564, Conclusion and recommendations: The results of this study reveal a high prevalence of MSDs among social security workers in Dar es Salaam. These findings serve as a crucial alert for employers and employees to develop and review existing ergonomic interventions. It is also recommended that the government strengthen and regularly conduct ergonomic training, inspections, and enforcement in all workplaces.
